Gutta-percha points filler in tooth root canal

Abstract

The invention discloses a tooth glue tip filler in tooth root canal, it consists of force application part, vessels and push bar part connecting the force application part, said vessels consists of shedding and guided groove through vessels, said push bar part consists of push bar equipped in guided groove and is relative to vessels sliding in guided groove. Apply external force on the force application part during the use process, the push bar moves relatively to vessel, the tooth glue inserting the guided groove from shedding is cut by push bar and fills into the 1 / 3 root canal of root tip to making the filled tooth glue tip is controlled in the required length range, it need not remove exposed tooth glue while blocks the tooth root tip hole to making the tooth root tip will not be filled over.

Description

technical field

[0001] The invention relates to a dental tool, in particular to a gutta-percha tip filler used in the root canal of a tooth during root canal treatment. Background technique
